Let me give you a full progress report before guesses are made.
Was presented a CDX unit that was not reading CD games, Genesis carts play fine but CD does not spin and screen says "no disc"
Unit has original OEM power supply.
Upon opening the unit I took note that the copper shielding inside had many fingerprints on it denoting that someone had been inside before, however there is no evidence of any solder work done, leading me to believe they were just in there to try adjusting pots. There is no evidence of leaky or bulging caps either.
I wired a battery to the spindle motor and it spun freely with no issue so the motor is good. the laser shaft assembly also moves easily so it is not seized.
Further testing upon being reassembled, the door close switch is working as the screen notifies me when I open the disc cover.
One interesting thing is that if I force the laser to the outer track position and turn the system on the disc will spin clockwise for two seconds then reverse for a second then stop, this will sometimes result in an unending "checking disc" message or a "no disc" message.
I am guessing that the unit needs a new laser assembly, but if someone did in fact fondle with the pots it would be incredibly hard to find the correct pot designation.
Any suggestions or recommendations would be appreciated
